Subj: Network concerns
Dear All,
There are a couple of points I would like to call to your attention:
1) Several individuals (myself included) have experienced a considerable time
delay from the moment they send their message to the A-E network until the
message is actually posted. I have no explanation for the delay, other than
to suggest it is directly related to the rate at which the winter thaw
proceeds in Saskatoon. Just as Saskatoonians realize that eventually
the Province will heat up and the mosquitoes will emerge, you too can be assured
that your message will eventually be posted on the A-E network (or forwarded to
cyber space in the hopes of contacting alien life forms). Either way, it is
best to wait an hour or so before you repost your message.
2) If you wish to unsubscribe from the network, or tell a friend they should
subscribe, please remember to send your request to:
Applied-ethology-REQUEST@sask.usask.ca (This goes to the list-server)
DO NOT send your SUBSCRIBE or UNSUBSCRIBE request to:
Applied-ethology@sask.usask.ca (This goes to the entire network)
Notice the difference between the two addresses? If you are having trouble
subscribing or unsubscribing send a message directly to me (not the entire
network) at:
stookey@sask.usask.ca
Hope this helps!
Joe Stookey
P.S. Occasionally someone wants to unsubscribe, because the A-E network does not
discuss the applied-ethology topic(s) they are interested in discussing. In
such cases, it is best to post the message directly to the entire network,
stating your request to unsubscribe and the behavioural topic you had hoped to
discuss. I can then remove your address from the mailing list and we can begin
discussing the topic, once you are gone! This is a well thoughtout strategy
that the original organizers of this network have all agreed to adhere to. If
you have a topic that you secretly hope will be discussed, but you never
raise the issue, we have agreed to honor your secrecy and we will not openly
discuss the topic in your presence!

Subj: Urine drinking in pigs
Dear All,
Does anyone have any information or references concerning the behaviour of
urine drinking by swine? I had a veterinarian call me about a client with pigs
in a confinement operation (weighing > 35kgs) that were actively drinking
urine from the other pigs. Water quality or quantity do not seem to be an
issue. The vet, herself, observed some pigs drinking urine, some were observed
trying to drink directly from the sheath of castrate males. I have not been
successful at finding any references that mention this behaviour.
Any ideas or references would be appreciated.
Thank you in advance.

Subj: RE: Hens & red light
Dear Rebecca,
According to a book I saw recently, chickens can perceive a range of
wavelengths similar to humans. According to this source they may see better
in red light than in shorter wavelengths. Also given is the effect of
different lighting colours on some developmental and production parameters.
However the authors don't reference the source of this information, but
presumably somebody did the research.
Hope this helps. (?)

I believe someone out there has been studying the severity of pain by
giving animals access to drinking water with or without anaesthetic

different causes of pain.
This is very elegant and I want to read about it. I could go through

People often use the fact that an animal is eating as evidence that its welfare
is OK. This seems common sense but I wonder how good the evidence really is. A
reduction in food intake doesn't seem very useful when examining how animals
react to acute stress. Certainly among rodents the phenomenon of stress-induced
eating seems well established, although I have not seen much on this in farm
animals. I have done some experiments with sheep (unfortunately unpublished),
which suggested such an effect. I was examining the stressful effects of
different handling techniques. What I found was interesting in that the effect
of the handling technique seemed to depend on where the treatment was applied.
If I went into the sheep's home pen and restrained it (inverted in a sheep
handling machine, with simulated shearing), then for an hour or so after, food
consumption was reduced. However, if I took the sheep out of its home pen,
restrained it in the same way, and then returned it to its home pen, food
consumption was actually increased; the sheep generally started eating
immediately they were returned to their home pens. I thought this might be
explained by assuming that the sheep think of their home pens as a "safe
place". Does anybody know of research on stress induced eating in farm animals?

i don't know of a specific incidence of feeding/watering animals w/any
analgesics/anesthetics in regard to stress/pain....
having said that, there is a large literature on free-feeding/watering
opioids (esp. morphine) in single and binary choice situations among
rodents. there are large strain differences in binary choice tests (both
acute and long term expts) and morphine selection is strongly influenced by
dietary factors (specifically, level of dietary fat and carbohydrate). not
surprisingly, opioid drugs also effect choice in cafeteria feeding
expts...increasing the %fat selected in the diet.
similar work (i.e., free choice or selection) has been done with alcohol,
cocaine, amphetamines and several other pharmacologic compounds.
since there are sizable individual differences in free choice feeding of
these compounds independent of stress, and each has its own set of
physiological and psychological outcomes (as would simple analgesics, like
aspirin/tylenol) i would be suspect of any value in evaluating stress, per se.
just my $.02.

Subj: "stress" induced feeding
Dear all,
re: "stress" induced feeding in farm animals.
I recollect reading a paper sometime ago in which production data for
lambs were related to their position in the shed (the ewes and lambs were
housed in small group pens along the length of a large
barn). It was reported that the lambs nearer the doors put on weight more
quickly. I wrote to the authors asking what their explanation for this
was. They suggested this was due to the alarm response of the lamb.
When disturbed they run to the mother and subsequently start suckling.
Because those animals nearer
the door were disturbed more frequently, they fed more frequently and
subsequently put on weight more rapidly.

trained to self-administer narcotics will use them in response to painful
stimuli (Zimmermann, 1986)." The cited reference is: Zimmermann, M.
